1 Claim'.

This invention appertains'to new and usefulV improvements in dispensing 'apparatus and more particularly to a safe dispenser for dispensing acid and'other dangerous substances,4

The principal obi-ect of the present inventionis to provide an apparatus' fordispensing acid or other dangerous vsubstances in certain predetermined amounts and into receivers in such a manner that none ofthe substance can spill or in any way escape, and to the end that a mul-` titude of tests, such as in ascertaining the but-- These and various other-important objects and advantages of the invention will become apparent to the reader of the following specification.

In the drawings: Y

Figure 1 represents a front elevational view of the dispenser with a portion'in section,

Figure 2 is a side elevational view of the dispenser with a portion in section,

Figure 3 is an enlarged fragmentary detailed sectional view showing one of the cylinders in dumping position,

Figure 4 is a top plan view of the tray,

Figure 5 is a section on the line 5-5 of Figure 4,

Figure 6 is a perspective view of one of the cushion disks,

Figure 7 is a side elevational view of one of the cylinders with a portion in section,

Figure 8 is an end elevational view of one of the cylinders,

Figure 9 is a side elevational view of one of the cylinder sleeves with a portion in section,

Figure 10 is an end elevational viewoi one of the sleeves.

Referring to the drawings wherein like numerals designate like parts, it can be seen that the dispenser consists of an upper glass jar 5 having a filler neck 6. On this neck 6 is a cap I having a vent 8.

Numeral 9 denotes a glass'plate of substantial thickness located below the bottom of the jar 5. A resilient packing gasket I0 is interposed between the bottom of the jar 5 and the plate 9.

A supporting frame is provided and consists of a box-like base made up of a front wall Il,

side walls I2 and a back wall I3 and fromy the corners of this box-like structure rises the posts I4. -The posts are connected at their upper portions by an upper frontwall l5, side walls I6 and a rear wall I'I and these upper Vwalls are bridged by a cover plate I8 secured toI the upper walls by screws I9, thisl cover I8 being formed with an opening through which the .neck 6 and cap 1 can protrude. It is to be understood thatthe box-like structure forming thebase portion of the dispenser; the post It and the upper walls Y and cover plate I8 are all of hard rubber, pref-V erably.

` It "can also be seen their inner sidesv to receive the corner portions of the-jar 5 and plate 9, the plate Q rresting at its corner portions on the shoulders 2t of the postsllip.'

As can-be seen in Figure 1, the opposed portions ofY the jar bottom 5 and the plate 9 are bored to receive aplurality of parallel sleeves 2 I. These sleeves as shown in Figure 9 are of glass,

each having a -row of openings 22 at its upperv portion and a rowof somewhat larger openings 23` at vits lower portion, and the forward end of each of these sleeves 2| is provided with upwardly and,downwardlyextending lugs or tongues 2d which are received in recesses in the bottom of the jar 5 and plate 9 to prevent rotation of the sleeve 2l.

As can be seen in Figures 2 and 3, the-openings 22 in each sleeve 2| register with a corresponding port 25 in the bottom of the jar 5, while each large opening 23 in the bottom of the sleeve is opposed to a funnel-like port 26 extending downwardly through the plate 9. 'I'he bottom side of the plate 9 at the outlet of each of the funnel-like ports 26 is formed with a channel 21 circumventing the port openings to define a depending skirt 28 which can depend into the neck A of a vial or other container B.

As canA be seen in- Figures 3 and '7, an elongated cylinder Z is disposed in each of the sleeves 2l and each of the cylinders 29 has a plurality of pockets 30 therein, equal in number to the number offopenings 22 in the corresponding sleeve 2I. These cylinders 29 are also of glass and each Yhas a shank 3| projecting from its forward end over which an apertured block or knob 1'32 is litted a pin 33 being suitably extended 'rsNr osrica -j f in Figures i and 2, that the posts It at their upper portions are reduced at 21 l Y tion shown in Figure 1 to the position shown inV Figure 3 so that the contents can be dumped into the funnel-like, ports 26 to flow into the" via1sor other receptacles B.

.It can also be seen thata cross-bar 34ris pro-y vided at the front side of the apparatus and lover-- Y laps the upper lugs 24 Aso that there is no likeli- V hood of the sleeves being permitted to rotate or become dislodged from the position `shown. in Figure 2.- Y

A screw shaft 3 5 has ends journalled in the .front yand Vrear walls of the lower boXlikebase of the frame andthe forward end is equipped with a crank 36 whereby the shaft can be rotated.

The removable bottom 31 of the boX-likebase has upstanding flanges 38' to which certain ends of link members 39-39 rare pivotallyv secured These link members 39--39V arepart'rof a lazy tong arrangement which enclose a pair' of nuts 40-40 to which the remaining ends of the links 39e-39 are pivotally secured. This lazy tong assembly further consists of a pair of links 4I-4I, 'certain ends of which are pivotally se-V cured to depending anges 42 on a follower plate 43lwith the remaining ends o`f the links.4l bein pivotally secured to the nuts 40. Y

'I'he screw 35 has right and left hand threads 44, 45, A'and obviously, when the vshaft 35 isrotated by thehandle 35,'the nuts 40 areV separated or brought together, depending Vupon the direction of rotation, for 'the purpose of raising or lowering the follower plate 43.

On the vfollower platev 43 is a tray V46 which y. has a plurality of pockets 4"l1 therein for receiving the'base portions of vials Cfor other receptacles. In each of these pockets 41,0f the tray 46 is a cushion disk 48 'for supportingV the corresponding vial B. The forward end of the tray 46 is provided with a hand1e 49 so that the same may be Y claimed as new is: g Y An apparatus for dispensing liquids into'test readily slid forwardly on the follower plate '43 when the plate '43 has been moved to a lowered position with the upper ends of the vials B removed from the dispensing skirt 2s, as substan- V tially shown in dotted lines in Figure 1.

.Having described the invention, what is vials orv the like comprising a boxlike casing in- Acludingra lower'open top chamber, a atbottom liquid containing tank removably mounted in the upper part of said casing and having rows of liquid Vdischarging apertures in the bottom thereof, a horizontally extending plate in the casing -below the tanksupporting the latter and having rows of funnel Yshaped'discharge ports therein, the rows ofzdischarge ports registering with the rows of., discharge v apertures, semi-circular -groovesinjthe bottom of the tank andthe top of said plate Ymating and forming @horizontal cir-'- cular bores parallel'with and intermediate registeringrowsl of aperturesfand ports, cylindrical measuring vand dispensing cores rotatably mounted in saidv vbores forl receiving liquids discharged ,from said-aperturesand emptyingthefs'ame into saidvports, a platform at the top of the chamber lfor supporting vials beneath said discharge ports -and verticallyv movable to elevate the `rnouths of the vials up to said ports, and means inthe chamber operated to move saidplatform,l said casing being openatits sides between said plateland platform to rendervv the vials visible during lling.
